We need to well control the casting molds when manufacturing aluminum die casts, and to make temperatures of the molds reach 200 degrees. We should use mold temperature controllers for aluminum die casts so as to accurately control the temperatures.

We need to repair mold surface damages timely and adjust inclinations of the molds in order to improve finishes of mold surfaces and make even force of knockout pins when we adjust them.

After a period of time, we ought to replace the release agents in time, and then reasonably adjust iron content and cooling time of aluminum alloy and timely modify flow gates.
